Re: 1947 super clipper rear courtesy light

The front and rear lights are in two separate looms and not connected in any way except they both get power at the same time from the same aux fuse on the headlight switch. In the factory wiring diagrams that power supply point is labeled body feed and in the AEA diagrams, to body lights.
While I show 3 distinct postwar looms above, even if both courtesy light options are installed there are only two of them used in a 4 door sedan. Front loom is the same for all but the rear loom varies depending on model and how many lights are located in the rear seat area. It is possible to interconnect the looms so all lights work when any door opens but since the rear door switch wire runs overhead it would be difficult to do properly without damaging the headliner. If the headliner is out then easy to do. A wire could also be run under the carpet to connect directly to switches. While not as easy since it would require working a bit blind at one spot, not impossible. One possible downside is if all the lights and switches are interconnected using the pillar switch would also turn on the front lights. NOTE: This interconnect possibility is for postwar Clippers only. The 41-2 models may be different because some prewar front courtesy light options had the door switch interrupt power instead of providing the ground.
I have not seen a 2 door wiring diagram or car up close enough to know what the differences might be and exactly how or where any lights are placed. There may just be a single loom for all the lights with the doors or a pillar switch turning them all on. Perhaps someone with a 2 door can explain the operation or if the rear lights just operate with a pillar switch or go on with a door opening.
